**Vein angular** (V. Angularis) is an artery in human anatomy, which is located on the lateral side of the mandible at the level of the third molar. It runs from the lower border of the coronoid notch to the angle of the lower jaw, where it divides into two branches, each of which continues to supply the muscles of mastication and teeth.

Development and structure The artery starts from the inferior vein of the artery of the upper jaw, passes through the lower jaw and enters the masticatory muscle through the angle of the lower jaw. It consists of three layers: the outer connective tissue layer, the inner muscular layer and the middle vascular layer.

Innervation The angular vein is supplied by nerve fibers from the superior constrictor cervicalis. Innervated by the muscular plexus that covers the artery and the ganglia located in the superior transverse fascia of the neck.
